Omyabond 420

Omyabond 420 by Omya is an ultrafine, ground calcium carbonate (GCC) filler. It exhibits excellent bond strength and mechanical properties. It offers improved storage stability, workability and ridge holding along with best cost/performance ratio. Due to its smaller particle size, Omyabond 420 provides shear thinning and excellent adhesion on wood. It is designed for moisture curing parquet adhesives such as silyl modified polymers (SMP), hybrid, silicone and polyurethanes. It does not influence viscosity upon accelerated storage, even without pre-drying the formulation.
